Who's that girl?! Why it's Jennifer Aniston of course! The actress went for an incognito look when she wore a fedora, sunglasses and scarf to a Los Angeles spa on Friday afternoon. Disguise or no disguise -- we can spot that signature square jaw anywhere!

While we hadn't seen Jen and fiance Justin Theroux for awhile, we spotted the Horrible Bosses 2 star and her main man Christmas tree shopping yesterday and the today the star's engagement ring is still front and center. So it looks like all is well in love land!

Pregnancy rumors have been swirling for months. Back in September Us Weekly reported that Aniston and Theroux were expecting their first child together, but since they ran that as a cover story, there haven't been any further mentions of the 44-year-old actress having a bun in the oven -- and Jen doesn't look like she has a baby bump to us!

Recently, People.com reported the couple has put their plans for a wedding and kids on hold, however the story was subsequently taken down. A source told the mag, "She had included her friends and seemed excited [about the process]," but then decided "she needed to focus on work." The insider added, "There was a lot of baby talk in the past, but she is not focused on it. She's aware her age makes it more difficult. Her attitude is, 'If it happens, great, but if it doesn't, it wasn't meant to be.'"
